Noticed High ZFS memory usage in 11.3.35 . Is this memory recoverable ? Rhel servers do similar think with ext file systems and its cache memory process
available. Is that the case with ZFS on solaris 11.3/4 or should I cap it to improve performance for applications requiring memory like Oracle forms, i.e
set zfs:zfs_arc_max=10737418240 ?
